Abstract: Government innovation could be studied in the dimensions of time， space and time-space from the perspective of process theory. In the time dimension， government innovation is a dynamic cycle comprised of generation stage， implementation stage and diffusion stage， and each stage could also be divided into several specific steps. In the space dimension， government innovation is a dynamic system in which government innovators， government innovation environments and government innovation functional factors tend to congregate， associate and interact with each other. In the time-space dimension， government innovation is a journey full of mutual embedding， interweaving and symbiosis evolving between the government innovation temporal procedure and government innovation spatial elements. Highlighting the construction of feedback mechanism in the time dimension， the optimization of government innovation's ecological system in the space dimension and the synergy of government innovation journey in the time-space dimension is of great importance for the effective integration and optimization of the government innovation process.

Key words: government innovation, process analysis, time dimension, space dimension, time-space dimension
